I have read a lot of reviews on after market magazines. Up to about a year ago, Pro-Mag did not get ratings that were very good. I attemped to try one for fit at a local gun show, and the fit and finish just did not seem correct. Alot of grind going in and hard to release coming out. Just a bit to large in some spot. Walked away and bought a Magazine direct from Eagle Imports in New Jersey (Bersa). Very pleased with the factory Mag., and great group to deal with so far. I have also changed my grip when firing the weapon as others have stated. I am not getting my 7th round jam/stovepipe any longer. I can not say if it is the new Mag Spring, or the Grip.

Good luck with you issue, try grip change first, less expensive. I am so pleased with the Thunder 380 I just purchased a second wepon for my Son's Birthday. Great Firearm for the money.

Can you elaborate on "grip change"? Exactly how are you holding the pistol that makes it more effective?

Im no expert but it seems to work. I read that you should hold the pistol with your strong hand tight enough so as to just start to quiver, not shake, just a very strong grip. Exhale half breath goes out Squeeze the triger once sight picture is where you want it. Keep hands strong. I have included the site I read this on. Hope it helps. Im sure that others in this forum can be a better source of info. The Bersa 380 as stated earlier is a fantastic firearm.

sounds like a mag problem as most everyone is saying. i had a 22 that did the same thing cuz the mag follower would get stuck almost all the way to the top. i just tore the mag apart scrubbed the inside for derbris, checked to see if there was any kind of bend or ping that would catch the follower. then last i tugged on the spring, since it was a really old 22, but that worked for me...

As an update, I shot another 60 rounds Friday night swapping between the original Bersa mag (black) that came with the gun and a new Bersa mag (stainless). I was using different target ammo this time (basically whatever the range has because I have to purchase and shoot their stuff). Anyway -- flawless. Not a single FTF, FTE, etc... I really paid attention to my grip and shooting process. I shot quite accurately -- at least for me. I'm feeling much better now. Maybe it was just break-in / ammo / grip issues.

...As I originally wrote, you were limp-wristing.
It wasn't the magazines.

Still not convinced of that. The problem only happened on the last round of just about every magazine (or the firing of the second to last round). Is limp wristing a typical pattern of behavior that only happens when firing the second to last round of a magazine? Not trying to be defensive about my grip, it just doesn't seem a likely cause. If it was happening more randomly, then I'd tend to agree.

Seems more like magazine break-in, or maybe I did a better cleaning between these two outings.

It appears you've resolved your problem. But I have to say, I've been a member of the Bersa chat forum for a couple of years and I highly recommend going there for any Bersa related issues you may have. And, in my experience and opinion, I have to totally disagree with the earlier statement statement that "They are as unfriendly a bunch as there is on the web" .
